Fact-checking the U.S. Chamber on Alan Grayson

The U.S. Chamber of Commerce is using it against him in a TV attack ad airing in May 2012. Grayson, who represented House District 8 until Dan Webster unseated him in 2010, is running for a new Orlando seat.

The commercial is part of a broader campaign by the lobbying group targeting Democrats over their support of "Obamacare."
